BUTTON ATTACHING MACHINE.

Spe'cification of Letters Patent.

Patented Feb. 3, 1920.

Application filed July 20, 1918. Serial No. 245,804.

To all whom. it may concern:

Be it known that 1,. CHRISTIAN H. T. HAGELSTEIN, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Button-Attaching Machines, of

which the following description in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to machines of the type shown in U. S. Letters Patents 1,063,885, dated June 3, 1913, and 1,099,254, dated June 9, 1914, which are constructed to attach shoe but-tons to shoe tops or other material.

These machines comprise button-sewing mechanism and a chute or race way arranged to deliver the buttons singly to the buttonsewing mechanism with the eye or shank of the button in proper position to receive the needle of' the sewing'meehanism. The construction shown in the above mentioned patents is designed to operate with shoebuttons having a flat-under face. It is some times desirable to utilize shoe buttons which are provided with a central projection or protuberance on the under face, and the object of the present invention is to provide an improved form of chute or race-way which will permit the us of buttons of either style, that is, buttons which have a flat under face or buttons which have a protuberance or projection-for1ned on the under face.

In order to give an understanding of my invention I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features, will be pointed out in the appended claim.

Figure 1 shows a portion of a button-sewing machine embodying my inventlon.

Fig. 2 is an enlarged sectional view on the line 2-2, Fig. 1.

Fig. 3 is a section on the line 3--3, Fig. 2.

Fig. 4 is a section on the line 4-4, Fig. 2.

Fig. 5 is a section on the line 55, Fig. 2.

Fig. 6 is a view of a shoe button.

Inasmuch as the present invention relates solely to the chute or race-way, I have not deemed it necessary to illustrate in the drawings a complete button-sewing machine. I have, however, shown at 1 a ortion of the head of the machine in whic reciprocates the needle-bar 2 forming part of the'buttonsewing mechanism, and I have also shown at 3 a portion of the button-containing hopper, and at 4 I have shown the chute or raceway through which the buttons are delivered to but-tonattaching position, in which position they are acted upon by'the button-sewing mechanism. The chute or race-way is provided with a stud 5, which is pivoted in a bearing 6 formed on the head 1, suitable means being provided to oscillate the chute and hopper in timed relation with the movements of the button-sewin mechanism all as shown in the above mentioned patents.

The chute or race-way comprises the front section 7 and the back section 8 which are adjustably secured together by means of adjust-ing screws 9. The space 10 between the front and back of the chuteconstitutes the space in which the buttons 11 are received, and the front 7 of the chute is formed with a groove or kerf 12, which extends from the hopper 3 to the lower end of the chute and in which the shanks or eyes 13 of the buttons are received as they travel down the chute.

The parts thus far described are or may be all as shown in the above mentioned patents and constitute no par-t of my present invention.

There are some shoe buttons made after the manner shown in Fig. 6, that is, that body 11 of the button is formed with a pro]ection orprotuberance ll extending from the under side thereof, saidprojection or protuberance having the eye or shank 13 extending therefrom. Other shoe buttons have a flat under face as shown in Fig. 4 of the above mentioned patent, No. 1,099,254. Buttons of the type having the fiat under face as shown in the-above mentioned patent have a larger or longer eye or shank than buttons having the construction shown in Fig. 6 and which are provided with the central protuberance 14. In order that the buttons may .be sewed properly to the shoe top or other material it is essential that the eye of the but-ton which is at the lower end of the chute in button-attaching position should project sufiiciently beyond the front face of the chute to permit the needle to pass through said eye or shank, and in order that this result may'be secured when buttons of the type shown in Fig. 6 are used I propose to mac e the front section of the chute with the beveled or chamfered edges 16 at the open side of the kerf 12. These beveled or chamfered edges form a countersink or groove adapted to receive the projection or protuberance 14 so that the flat edge 18 of the button may rest against the face 19 of the front chute section 7 With this construction at the delivery end of the chute the shorter eye or shank 13 projects sufliciently beyond the front face 20 of the chute so that the needle will enter properly the eye or shank.

The beveled or chamfered edges 36 may extend throughout a greater or less po 'tion of the kerf 12, the important thing 10 ing, that they exist at the lower or delivery end of the chute so that when the button is in attaching position the shank or eye 13 thereof will project through the front of the chute a suflicient distance to permit the needle to pass therethrough.

In the preferred embodiment of my in vention I propose to extend the chamfered edges 16 to the top of the chute and to bevel the edges 16 a progressively decreasing amount from the lower to the upper end of the chute. At the upper end of the chute the beveling or chamfering of the edges is practically nothing, the amount of bevel or chamfer Increasing progressively from the top to the bottom of the chute. The purpose of this construction is to avoid any possible interference with the delivery of the buttons to the chute from the hopper 3.

The presence of the groove formed by the ehamfered edges 16 does not interfere in any way with the use of the chute in attaching buttons having a fiat under face as shown in said patent No. 1,099,254, because when flat-faced buttons are used the peripheral portion of the flat-face will rest against the face 19 of the front chute section and the button will thus be supported in the same position as if the chute were not provided with the chamferededges.

It will be noted that the race-way is formed with a slight depression 26 at its lower end. This depression is so situated that the button which occupies it will be in button-attaching position, and said recess therefore constitutes a button-positioning recess for the button which is in buttonattaching position.

The machine illustrated in Fig. '1 is. of the type adapted to sew a button to the shoe top or other material, but my invention is equally applicable to button-attaching machines constructed to attach a button to the material by means of a wire or other attaching element.

I claim:

Ina machine for'attaching buttons each having a central protuberance on its under face, the combination with button-attaching mechanism, of a chute for delivering buttons thereto, said ch'ute comprising spaced front and rear sections betxeen which the buttons are received, the front section having a shank-receiving groove which is provided with a flaring mouth of progressively-increasing Width from the entering to the delivery end of the chute, said mouth at the delivery end being of sufiicient transverse dimension to receive the protuberance on the button, but of less transverse dimension than the diameter of the button whereby each button at the delivery end will be supported by engagement of the under face of the button outside of said protuberance with the face of the front section.

In testimony whereof I have signed my name to this specification.

CHRISTIAN H. T. HAGELSTEIN.
